摘要

The electrochemical oxidation of paper industry wastewater was studied using two types ofdimensionally stable anodes: Ti/RuO2 and Ti/RuIrCo(40%:40%:20%)Ox. The electrodes werecharacterized using SEM micrography and EDS spectroscopy. The local mapping analysis wasperformed on Ti/RuIrCo(40%:40%:20%)Ox. The presence of Ir and Co significantly modified thesurface morphology of Ti/RuO2. The oxidation process was analyzed as a function of the electrolysistime at a constant cell potential in the absence or presence of an electrolyte (NaCl) and at an initial pHof 6.2. The effectiveness with which the two anodes electrochemically oxidized the wastewater wasevaluated by measuring the removal of the chemical oxygen demand (COD), color, and totalpolyphenols, and using UV-Vis spectroscopy. The results revealed that both anodes reduced the COD,color, and polyphenols; however, the ability to remove organic matter depended on the nature of theelectrode material, the presence or absence of NaCl, and the electrolysis time. In the absence of NaCl,the effectiveness of the Ti/RuO2 electrode exceeded that of Ti/RuIrCo(40%:40%:20%)Ox for theremoval of COD, color, and polyphenols. The presence of NaCl was a determining factor in theprocess of electrochemical oxidation. In the presence of NaCl, both anodes increased their capacitiesfor removing the COD, color, and polyphenols; however, the anode Ti/RuIrCo(40%:40%:20%)Ox wasmore effective than the anode Ti/RuO2 in reducing the COD. The UV-Vis spectrum suggested.
